WINDOW SCREEN MOUNTING.

Application filed December 2, 1927. Serial No. 237,237.

This invention relates to window screen mountings and has for its object the provision of simple but effective means whereby the screen will always be centered in the window frame on guides which are each provided with a lower portion adapted to be I invention consists can be variously arranged and organized, and theinvention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents a front elevation of a window casing with a screen mounting therein embodying the principles of the present invention.

Figure 2 represents a similar elevation with the screen raised and oneof the guides therefor in position for removal.

Figure 3 represents a vertical section of the same showing both sashes and screen in the casing.

Figure 4 represents a vertical section of a portion of one of the screen guides.

corner of the screen.

Figure 6 represents a vertical section of ings.

In the drawings 10 is a window casing provided with the lower sash 11 and the fupper sash 12.

In the rear of sashes 11, 12, the casing 10 has secured to the opposite sides thereof, the vertical guide members 13 and 14.

The guide members 13 are U-shaped and formed of metal with similar guide members l4 telescoping therein so that when positioned in the casing 10 each pair of guide members 13, 14, extend from the top to bottom of said casing.

By making each lower guide member 14 so that its upper end 15 will telescope into the lower end of the upper guide 13 the two members 13, 14 may be adjusted to fit window casings of different heights.

The upper guide members 13 are permanently secured to the sides of the window casing by nails 16 having heads 17 which are positioned in depressions 18 formed in said guide member.

The lower guide member 14 has indentations 19 formed in the sides thereof which extend toward each other and are adapted that the guide member 14 will be prevented from moving endwise.

The indentations 19 coacting with the heads 20 of the staples 21 prevent any accidental displacement of said lower guide members 14.

When the guide members 13, 14 are in position as shown in the drawings the screen 23 may be moved endwise thereof, this F lgure 5 represents a vertical sectlon of a screen having grooves 24 into which the guides 13, 14 extend.

Within these grooves 24 are ositioned a plurality of leaf springs 25, eac spring being secured at one end only to the screen frame 23 by a screw 26.

These springs 25 tend to retain the screen 23 in the center of the window casing and furthermore make it possible for the same screen to be used in window casings having different widths.

The lower ends of the grooves 24 are deeper at their lower ends as indicated at 27 in order to permit the removal of the lower guide members 14 which have the u per ends 15 curved as at 28 to permit said guide members being moved into the position indicated at the left of Fig. 2 preparator to their complete removal.

X's will be noted in Fig. 1 the lower ends of the guide members 13 are above the top of the screen 23 when in its lowest position.

lVhen it is desired to remove the screen 23 from the window casing 10 it is raised to the upper end of the casing 10 as shown in 'Ihe lower ends of the lower guide members 14 are disconnected from the staples 21 or other fasteners and are entirely removed from the casing 10.

The screen 23 is then lowered and as soon as its upper edge passes the lower ends of the upper guide members 13, it may be removed easily from the casing 10.

By constructing the screen mounting in themanner shown and described, the same screen is adapted to be used in different windows of varying dimensions, and will always slide freely on the guides 13, 14, regardless of weather conditions.

By. making the screen guides in two parts telescoping into each other, the same guides mav be quickly installed in windows having different heights and by making the lower f guide members 14 removable the screen By the use of the mounting herein described this is entirely unnecessary.

Ordinary screens are liable to be too loose under certain weather conditions and tootight under other weather conditions, but with the screens constructed and mounted as herein described there will never be any of these difficulties to contend-with.

Another great advantage of my mounting is that the screen can be easily positioned in the casing and removed therefrom without injury thereto.

, It is believed that the operation and many advantages of the invention will be understoodv without further description.

Having thus described my invention, I claim:

1. Ina screen frame mounting, a guide for said frame in two parts of which the upper part is adapted to be permanently secured to a window casing and has a walled recess at. its lower end while the lower part is adapted to be detachably secured at its lower end to said casing with its upper end inserted into the walled recess at the lower end of the upper part, with the outer faces of the two parts in alinement.

2. In a screen frame mounting, a U-shaped guide for said frame in two parts of which the upper part is adapted to be permanently secured to a window casing with its open side toward said casing while the lower part is adapted to be detachably secured at its lower end to said casin with its upper end provided with a reduced portion inserted in the lower end of the upper part, the outer faces of the two parts being in alinement.

3. In a screen frame mounting, a U-shaped guide for said frame in two parts of which the upper part is adapted to be permanently secured to a window casing with its open side toward said casing while the lower part is adapted to be detachably secured at its lower end to said casing with its upper end inserted in the lower end of the upper part, said lower part being provided at its lower end with means adapted to engage a fixture on said casing and thereby prevent accidental lateral or end movement of said lower part.

4. In a screen frame mounting, a U-shaped guide adapted to be positioned in a groove of said frame and formed in two parts telescoping into each other with their outer faces in alinement, the upper part being adapted to be permanently secured to said casing with its closed end outward, and the lower part being provided with detents adapted to engage a shouldered fixture extending into the open side thereof from said casing.

5. In a screen frame mounting, a U-shaped guide adapted to be positioned in a groove of said frame and formed in two parts telescoping into each other with their outer faces in alinement, the upper part being adapted to be permanently secured to said casing with its closed end outward, and the lower part being provided with spring detents adapted to engage a U-shaped guide lock extending into the open side thereof from said casing.

6. In a screen frame mounting, a U-shaped guide adapted to be positioned in a groove of said frame and formed in two parts telescoping into each other with their outer faces in alinement the upper part being adapted to be permanently secured to said casing with its closed end outward, and the lower part being provided with detents adapted to engage a shouldered fixture extending into the open side thereof from said casing, the upper ends of the side walls of said lower part having their edges curved upwardly and outwardly to permit said lower part to be removed without disturbing said upper part.

7. In a screen frame mounting, a U-shapcd guide adapted to be positioned in a groove easing, said lower part having a length greater than the height of the screen coact- 10 ing therewith.
